Balloon dilatation of a bioprosthetic pulmonary valve.

A 37-year-old man with stenosis of a bioprosthetic pulmonary valve underwent percutaneous balloon valvoplasty. After the procedure the patient had moderate pulmonary regurgitation which has been well tolerated. The patient remains well with good functional capacity on follow-up at 2 years. Percutaneous balloon dilatation may be effective as a palliative procedure in the management of stenosis of a bioprosthetic valve in the pulmonary position.
